A4 Stand-By Blow-Down
If the controller or hygrostat demands no humidity from the humidifier
for a long period of time, it is advisable to flush out the cylinder water.
At Parameter A4 Stand-By Blow-Down, the time period is set after
which the complete blow-down is automatically performed. Water will
not be fed into the cylinder until a new demand signal is received.
A17 Stand-by heating
The stand-by heating keeps the cylinder water warm when no request
is pending. The heating takes place if the safety chain is closed at
intervals according to parameter C16 for the heating time according to
parameter C17.
C16 Interval time A17
The C16 parameter defines the length of the pause time between the
phases of the stand-by heating (active only if A17 = Yes).
C17 On time A17
The C17 parameter defines the length of the heating period for the
stand-by heating (active only if A17 = Yes.)
E1 Xp-PI-Controller
Boosting PI-controller = 100/E1 [Xp = 0 - 100%]
E2 Tn-PI-Controller
Reset Time PI-controller [Tn = 0 - 255 sec]
E5 Base Relay
The base relay provides a potentialfree two-way contact at terminals
28, 29 and 30 (rated load: 250V/8A) (see page 59).
It is activated if certain operational conditions apply. The operational
condition “collective fault” is preset.
It is possible to associate another operational condition with the base
relay circuit, also see Section: “Summary Table of Parameters” on
Page 35, “Parameter E5.”
E6 1. Transmitting Relay
The switching function of this relay is factory set to “Essence Injection”
and should not be modified.
The base relay provides a potentialfree two-way contact at terminals
31, 32 and 33 (rated load: 250V/8A).
